AUTOMATIC FLUID-CONTROLLER.

Specification of Letters Patent.

Patented March 31, 1908.

To all whom it may concern:

Be it known that I, Mono M. BORDEN, a citizen of the United States, residing at Collingswood, in the county of Camden and State of New Jersey, have invented certain Im rovements in Automatic Fluid-Contro ers, of which the following is a specification.

This invention relates to mechanism for automatically regulating the flow of a fluid to a predetermined rate. Its leading purpose 1s to provide improved means for controlling the fiow of water from a filter so that its rate shall remain the same throughout the usual variations in head due to irregularities in action. The characteristic construction com rises a conduit controlled by a valve whic 1 is subject to fluid impact induced by the head causing the flow to be. regulated.

In the accompanying drawings, Figure 1 is a sectional elevation representlng a form of the invention, Fig. 2 is a sectional elevation representing a second form of the invention, Fig. 3 is a sectional elevation re resenting a thlldform of the invention, an Fig. 4 is a sectional elevation representing aform of the mechamsm in an inclined position to support the weight of the movable arts.

As shown in Fig. 1, the lter 1 discharges through the conduit 2, having the upturned nozzle or restricted outlet 2, into the effluent In the conduit are the ports 2 controlled by the balanced valve 4 having a stem 5 connected with a balancing lever 6 which is fulcrumed on the bearing 7, the lever having thereon the adjustable poise 8 for counter-balancin the valve. A cup or hood 9 is fixed to the ever above the nozzle 2 111 position to receive the impact of fluid discharged therefrom. When the head induc- I ing flow through the conduit is at a minimum the valve is at its maximum opening. As the head rises the impact of the jet discharged through the nozzleagainst the cu increases, causing the valve to move towar the closed position, whereby the rate of flow is main tained through variations in head.

As shown in Fig. 2, the conduit 2 contalns the ports 10 controlled by the balanced valve 11 and discharges through the nozzle 12. A

stem 13 connects the valve with a cup or hood 14 placed over or in front of the nozzle so as to receive the impact of liquid. therefrom, the desired balance between the force of theimpact and the weight of the valve mechanism being obtained by means of weights 14 held by the stem 15 on the hood.

With the minimum head the valve mechanism falls to its lowest limit and opens the ports to the maximum. As the head rises the greater impact of the li uid ejected through the nozzle against the 00d moves the latter and the valve to effect a proportionate closure of the ports so as to maintain the rate of flow.

Asshown in Fig. 3, the conduit 2, having the ports 10 controlled by the valve 11, discharges through the orifice 16. The orifice is covered by a hood 17 connected to the valve by the stem 18; this valve mechanism being balanced by a lever 19 having a connection 20 therewith, a bearing on the fulcrum 21, and an adjustable counter-poise- 22. With the minimum head the valve opens the ports to the maximum and as the headincreases the im act against the hood moves the valve mec anism and gradually closes the ports so that the rate of flow is maintained.

As shown in Fig. 4, the desired balance of the valve 11 with the hood 14 may be obtained by inclining the casing .23 and the port cylinder 24, in which it reciprocates, to the angle affording the requisite degree of repose, so that the weight of the valve mechanism will merely overcome the frictional resistance and fall to open the ports 10 with the" minimum head and will rise to gradually close the ports with the increasing lmgact of the liquid escaping through the ori ce 12 against the hood 14.

Having described my invention, I claim 1. The combination of a conduit, with a valve, means connected with said valve for holding it normally in the open position, a device connected with said means for receivin fluid impact by which said valve is toward the, closed position, and

move means for directing a fluid jet against said device.

2. The combination of a valve, mechanism for balancing said valve, said mechanism having a device for receiving fluid impact, and a conduit having an orifice through which fluid is thrown against said device to regulate the position of said valve, said de vice being exterior to said conduit.

3. The combination of a -conduit having a contracted outlet, with a valve in .said conduit, a fulcrumed lever connected with said valve, and a device connected with said lever for receiving the impact of fluid discharged from said outlet.

4. The combination of a filter, an effluent chamber, a conduit leading from said filter to said chamber, said conduit having a contracted outlet, a valve for controlling the flow through said conduit, mechanism for balancing said valve, and a device subject to the impact of fluid discharged through said outlet for regulating the position of said valve.'

5. The combination of a conduit having an outlet, a valve for controlling said conduit, and means for receiving the impact of liquid discharged through said outlet and regulating the position of said valve, the

means for receiving the liquid impact being exterior to said conduit.

6. The combination of a conduit having a 20 contracted outlet, a valve for controlling said conduit, and a movable hood which covers said outlet, said hood being connected to said valve so that the movement of said hood by liquid discharged through said out- 25 let moves said valve.

In testimony whereof I have hereunto set my name this 23d day of August, 1907, in the presence of the subscribing witnesses.
